The Late Show‘s “resident rap duo” Run the Jewels ruined Stephen Colbert’s birthday Friday with a song that cruelly mocked the late-show host’s age.

“Skin all wrinkly / Muscles all softened / You don’t need a cake / You need a motherfucking coffin,” Killer Mike said in the atypical birthday track.

Run the Jewels frequently visit the Late Show on celebratory occasions and proceed to mar the moment, including Colbert’s Halloween and Christmas. For Colbert’s birthday, Killer Mike and El-P recorded a traditional “Happy Birthday to You” before opting instead to celebrate Run the Jewels-style.
